Answer:
22 ft
Step-by-step explanation:
To find the length of the side of a square you need to do the opposite equation for finding area.
So the equation for finding the area of a square is a - x^2, or a = x squared.
The opposite of this equation would be x = square root of 479 because the opposite operation of squared is square root.
Now you need to solve this equation
So x = square root of 479, the square root of 479 is 21.89
So the x equals 21.89 but you need to find the approximate length so you need to round. It says to round to the nearest foot so one side of the square is 22 feet long.
Answer:
So in order to find the missing number, we must find the difference with the numbers that we were given.
Problem #1
42-30= 12 and 84-69= 15. It's possible that each difference increases by one Let's see...
30+12= 42
42+13= 55
55+14 = 69
69+15 = 84
So for 1., all you have to do is keep adding the difference and increase it by 1 each time. If you wanted to keep increasing, you would add 84+16, then 100+17, etc.
Problem #2: As for the second one, I had trouble solving it, sorry :(.
Problem #3
3. For the third problem, 27-22= 5 and 9-1=8. It looks like each difference increased by 1.
27-22 = 5
22-6 = 16
16-7 = 9
9-8= 1
Answer:
5 x 3 = 15
Step-by-step explanation:
x15 = 3 is impossible, because if you multiplied anything by 15 you wouldn't get 3.
The answer is:
6.2, 4.6, and 1.3 because you are going from greatest to least greatest..
Hope this helps :)
